Table 6.1—Troubleshooting
Symptom
Cause
Resolution
Chip packing of the
bur
Too heavy a cut
Decrease width of the cut. Make multiple passes.
Not enough chip
clearance
Use a bur with less flutes. Refer to
.
The bur stalls.
Not enough or no drive
air
Verify that the drive air regulator is operating at 6.2 bar (90 psi) and
check for leaks.
Bur is not secure in the
collet.
Properly tighten burr in the collet
Too much side load
Decrease width of the cut. Make multiple passes.
The turbine motor must
be replaced.
Replace the turbine motor; refer to
.
The motor spindle is
sticking.
The motor bearings are
worn.
Replace the turbine motor; refer to
.
6.2 Service Procedures
CAUTION:
Thread locker applied to fasteners must not be used more than once.
Fasteners might become loose and cause equipment damage. Always apply new
thread locker when reusing fasteners.
The following service procedures provide instructions for user-serviceable parts replacement, when the
user chooses to service the unit in the field. For all service, it is recommended that the air supply (before
the solenoid valves) be disconnected. Drain any trapped air pressure in the lines. It is suggested that the air
supply be “locked out” to prevent accidental operation of the spindle.
6.2.1 Bur and Collet Replacement
In normal operation the bur will become worn. If improper feeds and speeds are used, the bur may
become “loaded” with material. In both instances, replace the bur. During initial production, the bur
and the work piece should be examined often in order to determine at what interval the bur should
be replaced. Replacing the collet will not be required when the same size of bur is replaced, but a
new collet is installed, when a different sized bur is required.
Refer to the following steps for replacing the bur and collet:
Refer to
.
Parts required: Refer to
Tools required: 7/16” (11 mm) and 9/16” (14.5 mm) open-end wrench
1.
Remove and/or lock-out the spindle motor air supply for safety. (De-energize all energized
circuits such as air and power).
2.
If the bur is to be replaced with one of an identical type, measure and record the tool length
extending beyond the collet lock nut. Alternatively, the optional ATI 9150-RC-T-4230 bur
setting tool accessory can be used to duplicate the tool exposure length.
3.
Use a 7/16” (11 mm) open-end wrench to hold the spindle just behind the collet nut.
4.
Use a 9/16” (14.5 mm) collet wrench to turn the collet locknut counterclockwise (when viewed
from the cutter tip) to loosen the collet.
CAUTION:
During operating of the deburring tool, the bur reaches high
temperatures. Failure to wear proper personal protection equipment or not
allowing the bur to cool could result in serious injury to the user. Be aware that
during operation, the bur becomes very hot, and when removing the bur, take
necessary safety precautions to avoid injury.
